6 FAQs about [Dual blade system wind turbine]

What is a dual rotor wind turbine generator?

This paper introduced a dual rotor wind turbine generator system, which consists of two rotors: one small auxiliary rotor at the upwind location and the other relatively larger main rotor at the downwind location.

Can a second rotor be used in a dual-rotor wind turbine?

The study focuses on the effect of introducing a second rotor to the main rotor of the wind turbine in what is called a dual-rotor wind turbine (DRWT). The numerical study took place on the performance of a small-scale model of a wind turbine of 0.9 m diameter using an S826 airfoil.

How does a dual rotor wind turbine work?

The dual rotors in front and rear side capture wind energy. The captured wind energy is transformed into high speed rotational energy by transmission system. In this Wind turbine the radius of the wind blades for the dual rotor is taken as 1.5m. The rated speed for the wind turbine is taken 10m/s.

How much power can a dual rotor turbine produce?

The scientific literature indicates that a dual-rotor system could extract additional 20-30% power compared to a single rotor system from the same wind stream. Our wind tunnel test indicates that a scaled-down version of the dual-rotor turbine system may produce up to 60% more power than a single-rotor system.

Are two-bladed wind turbines easier to install?

Two-bladed wind turbines are also easier to install. Whereas the three-bladed rotors spinning in today’s offshore farms must be assembled on site, two-bladed rotors can be preinstalled on the turbine’s machinery onshore; the assembled package fits more conveniently on ships and is light enough to lift onto the tower.

What is a dual rotor wind turbine gearbox?

In this paper author has designed of a gearbox of dual rotor wind turbine system. This gearbox composed of both compound and planetary gear train. The wind speed rotates the rotor of wind turbine 60-70 RPM in case of large wind turbines and 100-300 in small wind turbines.
